Marquam Nature Park includes part of the Marquam Trail, which connects to the 40-Mile Loop. The natural area includes many native plant species, including bigleaf maple, Douglas fir, red cedar and western hemlock. The park's entrance features a shelter with interpretive displays and maps.[1] The volunteer organization called Friends of Marquam Nature Park formed in 1968 after neighbors of the park successfully prevented housing development on Marquam Ravine.[3]

In 2013, Friends of Marquam Nature Park and the Regional Arts & Culture Council funded a mosaic project for one of the shelter's walls. The project cost $17,600; assembly is scheduled to begin in August and a dedication will take place in September following its completion.[3]
